Title:
Periodic glitch in sound with Firewire and snd-dice
Status in linux package in Ubuntu:
Confirmed
Status in pulseaudio package in Ubuntu:
New
Bug description:
I have a fresh installation of Ubuntu 17.10 with almost nothing extra
installed yet besides Bitwig Studio, Cadence and a few other things
from the KX Studio repositories.
Sorry if this is in the wrong place, but I did not find a way to
report bugs with kernel drivers.
But I also tried the bug after a fresh install with nothing else than
Bitwig Studio installed, it's the same.
I have a TC Electronics Impact Twin Firewire audio interface.
It is connected to a Iocrest SY-PEX30016 PCI-E card, which has a Texas
Instruments XIO2213BZAY chipset.
The ALSA snd-dice drivers work, but with glitches.
There is a periodic, glitch in the sound that sounds like a part of the
stream is missing, or something. It is steady in timing, nothing seems to have
an effect on it.
Recording seems to work. All outputs and inputs, also the ADAT outputs seem
to work, altough I could not test if the ADAT outputs feature the glitch too.
Seemingly randomly there might be a short maybe around 0.3 second
total break in the sound.
I'm not getting xruns at all.
I tried also Ubuntu Studio live USB, it has the exact same glitch. I
also tried a Native Instruments Audio2DJ USB interface, with that
there is no problem with the sound on my computer.
I tried also with Carla and ZynAddSubFx, and also with the live USB of
Linux Mint (current version), and the same glitch is present.
I tried also another Firewire controller card with a XIO2200A Texas
Instruments chip, it features the same glitch, but running a different speed.
In addition to that, I tried my motherboard's port that is run by a VIA 6308P
chipset. The result was close to my SY-PEX30016 PCI-E card, the same glitch. So
it is not connected to Texas Instruments specifically.
I had a KX Studio 14.x installation a few years ago, where the
interface was working without a hitch. But then I was running with
FFADO.
So to me it seems that the kernel integration of snd-dice has some
problem with timing with a TC Electronics interface?
I could not get FFADO to run with Jack now so I can't say if the FFADO
implementation would work.
